A. The graph f(x) = sin (x) is shifted a distance of ?/8 to the right, reflected in the x-axis, translated 7 units downward, then stretched vertically by a factor of 3. B. The graph f(x) = sin (x) is shifted a distance of ?/8 to the left, reflected in the y-axis, translated 7 units upward, then stretched vertically by a factor of 3. C. The graph f(x) = sin (x) is shifted a distance of ?/8 to the left, reflected in the x-axis, translated 7 units downward, then stretched vertically by a factor of 3. D. The graph f(x) = sin (x) is shifted a distance of ?/8 to the left, reflected in the y-axis, translated 7 units downward, then stretched horizontally by a factor of 3.
